The MPS®-i-125 EHV is a fully integrated behind-the-meter energy storage system that combines Raychem RPG’s efficient UL 1741 SA MPS®-125 EHV inverter with Li-Ion batteries in a temperature controlled battery NEMA-rated enclosure. BESS design is one of the most compact, easy-to-transport, wall-mounted bi-directional inverter, an ideal solution for island project requirement.

The highly compact integrated system is easily deployed on a concrete pad, crushed stone or on the ground with a forklift and minimal labor, reducing system installation costs for integrators and system owners. The system features Dynapower’s propreitary Dynamic Transfer™ which in the event of grid disturbance seamlessly switches a facility from grid-tied to battery backup power. Multiple MPS®-i-125 EHV systems can be paralleled together to meet the sizing needs of any behind-the-meter installation.

FEATURES:

  • AC Overcurrent Protection
  • DC Disconnect
  • Integrated DC Input Fuses
  • Redundant HVAC cooling systems
  • Fire Suppression System
  • All AC and DC Switchgear
  • DC Pre-Charge
  • Black Start (Optional)
  • Dynamic TransferTM

DYNAMIC TRANSFER TO OFF GRID MODE

The patented Dynamic Transfer™ algorithm monitors grid stability, and upon detecting a grid disturbance, disconnects from the grid. The equipment seamlessly transitions critical loads to stand-alone mode on the load connection and supports 100% phase imbalance in UF mode.

E COMP: AUTONOMOUS VOLT/VAR SUPPORT F COMP: AUTONOMOUS Hz/ WATT SUPPORT

A Volt Var function that provides immediate and automatic voltage support to the grid.

BLACK START

In the event of a complete system power outage, The patented Black Start restores power to the facility without the need for external power. Black Start technology can start distribution networks even with transformer magnetizing currents that exceed the power rating of the inverters. Multiple MPS®-i-125 EHV units can be restarted at once.

F COMP: AUTONOMOUS Hz/WATT SUPPORT

A Hz-Watt function that provides immediate and automatic frequency support to the grid.
